A new dimension in magnetism and superconductivity launched

01.11.2021

Barbora Budinska and Oleksandr Dobrovolskiy, in collaboration with D. Makarov, O. Volkov, A. Kakay and O. Pylypovskyi (HZDR, Germany) have presented a framework for expanding superconductivity and magnetism to curvilinear and 3D geometries. Their review and perspective paper summarizes the state of the art and outlines prospects for future research in this topical area.

In magnetic materials, the geometrically-broken symmetry provides a new toolbox to change magnetic responses relying on effects extrinsic to the material: curvature-induced anisotropy and chiral responses. In 3D nanomagnetism, of especial interest are artificial 3D frustrated systems, topology- and curvature-induced effects in complex-shaped 3D nano-architectures, and the dynamics of spin waves in 3D magnonic networks.

In superconductors, curvilinear geometry gives rise to topologically nontrivial screening currents and confinement potentials that stipulate the occurrence of different patterns of topological defects of the superconducting order parameter (Abrikosov vortices) and slips of its phase. The extension of superconducting nanostructures into the third dimension has already been demonstrated to improve the performance of superconducting quantum interference devices (SQUIDs), microwave bolometers and it advances investigations of 3D fluxonic circuits.
